To all whom itmay concern: i v

Be it known that I, BENJAMIN Orro FANSLOW, of the city of Los Angeles, in the county of LosAngele's, in the Upon the annexed sheet of drawings Figure 1, is a side elevation partly in section, of the mechanism or apparatus constituting my invention. Fig. 2, is a pla n of the same corresponding to Fig.1. Fig. 3, is an end elevationof the saidinachine; V Upon these drawings the table or platform upo which the machine, constituting my invention is carried, is marked A, and upon this table or platform the ;-flat metallic frame B, is mounted as shown. The flat 'metallic'frame B, is formed with a recess therein as shown by the'dotted line C, C, in-Figs. 1, 2, and3. In this recess thetype holder. D; is carried. The face of the type projects above the level of the type holder D, as shown by the dotted lineE, E, Fig. 1. "lmvards the end of the flat framing B, B, vertical studs F, are fixed preferably by being screwed therointo. Upon these studs the guides G, are carried; there being a hole in the end of each of the guides G, G, which correspond with the position of the studs F, F. The guides G, G,

3 are parallel with the face of the type E, E, forthe greater part of their length, and to insure the guides G,

parallel with the printing surface of the type. In each 4 of the pair of guides G. G, a slide-block I, is carried so as to be capable oi sliding backwards-and forwards in each'oi the guides G, G, each slide-block I, has a cylindrical hole thereinwhich constitutes the bearing for the axle J, of the impressionroller K, and upon the ends of the axles are the handles L, which the operator lays hold of by his hands to operate the machine by pushing the roller K, backwards and forwards. The printing ribbon indicated in Fig. l, by the line M, is *arricd upon the ribbon spool M, and it passes from Specification of Letters Patent.

oft the spool M, over the-supporting roller N; and.

thence beneath the printing rcllcr ii. and thenc stretching across or over the face of the type E, passing thence over the other carrying roller N on to theribbon winding spool 0 at the opposite end of the machine. The carrying rollers and NC'are supported by. end axles in bearings at eaclrend of the training B, as shown, and the spools M and O, arecarried upon two axles P, and Q, respectively, which again are fittedinto bearing blocks It, and S, fastened upon the table or platform A. Upon the axle of the spool M there is carried so as to be capable of slight angular or rotatable movement upon the said axle P, the lever T, having a short lever T, projecting'from its under part. In the act of printing, as the attendant pushes or pulls upon the handles L, L, accordingly as he moves the printing roller K, from or towards either end of the mechanical device constituting my invention, and

supposing him to be moving the same in the direction of the arrow marked X, in Figs. 1, and 2,oi the drawings, it results that the slide block I, comes in contact withthe upper end of the lever 'l,whe'n the lever T, is in the position shown in dotted lines in Fig. 1,- and that the lover I, continues to be moved around upon or with the axle P, upon which it is carried until the slide blocks I, have attained th'eir final position in their movement, that is to say, have arrived at ornearthe end of the'guides G. The contact'of the edge of one of the slide blocks I, forcestheleverT, into the position shown in full lines at Fig. 1, and atthe same time forces the leverT, into the position also shown in full lines in Fig. 1. To the lever T, there is pivoted one end of the connecting rod T the opposite endof which rod T is pivoted to the 1everT, carried uponthe axle Q, and so as to be. capable of rotating through a small 0 angle-thereon. The lever T,-is in the-position shown in tlie dotted lines in Fig. l,'wh'en the slideblock I,

, lever T, and the lever T, are in'the positions shown in dotted lines in Figi'l, then the lever T, ispushed from its position shown in dotted lines into the position shown in full lines in Fig. 1. ipon the lever T, there i is carried the pawl T, which engages with the teeth of the ratchet pinion T so that when the sliding block I has reached the position shown in full lines in Fig. 1, I and has moved the lovers T, and T from their position 1 0 shown in dotted lines, the movement of the lever T, is communicatedby the connecting rod T, to the lover T, which causes the pawl T, to move round the shaft Q, upon which the ratchet pinion T is carried, and

this movement of the iatchet pinion T, which is his 105.

toned firmly on the axle Q, causes the spool O, to rotate through a short distance and wind to an extent corresponding to that distance, a portion of the ribbon M, from off the spool M, and on t o the spool O. When the slide block I, is at the opposite end of the guides G, as

shown in dotted lines in Fig. 1, then the opposite contacting face of the-slideblock I, makes contact with the lever T, when the lever T is in'the position shown in dotted lines at the left hand end of Fig. 1, and moves the lever T, to the position also shown at the left hand end in lull lines. dill-10d to the full position, causes the pawl T to again move through the slight angle of rotation, and to again \vind off the corresponding length of the printing ribhon ill, from the spool M, on to the spool O. Bymeans ol' this part of the mcchanismit is obvious that by the winding off of a short length of the printing ribbon from the spool M, on to the spool O, that a fresh portion of printing ribbon is presented to the type or printing sur lace even at every stroke or horizontal printing move ment of the roller K. If, however, it is desired that the presentation of a fresh surlaee oi the printing ribbon be presented to the type or other printing surface at every other stroke of the roller -K, instead of at every stroke thereof then it is necessary for one only of the levers T, or T, to beoperatcd, in which case they may be disconnected by taking off the connecting rod T In operating the machine in this manner the printing ribbon would be moved at every alternate stroke or movement ofthe printing roller K, instead of at every stroke, at which a lresh surface of the printing ribbon would be presented to the type or other printing surface at every itll crnating stroke. I

It is to be understood that used for holding the types for printing within my new or improved machine a printers galley may be substituted by beingplaced in the recess which the type holder occupies, such printers galley, however, constituting no part of the.

present invention. It is'also to be understood that in place of operating the cylindrical roller {or pressing the paper to be printed upon the printing ribbon'by the hands or" an operator, the said cylindrical roller may be moved backwards and forwards in its slides or equiva lent guides by means of one or more toothed pinions geared into toothed racks to which the necessary backward and forward movement is imparted by the operator turning a handle as is well understood in operating rollers of various kinds,

Having now described the nature of my said inven- I tion I desire to observe in conclusion that what I con-.

sider to be novel and original, and therefore claim as the invention to be secured to me by Letters Patent, is

as follows:' I
